the bulging cap i need to replace is a 6.3v 1500uf.

the cap is on a pc motherboard.

is it acceptable to replace it with a 10v 1500uf cap?
 
thank you so much!

off to the soldering iron i go.
 
The rule of thumb with most electronic components is that higher voltage rated components are ok, never use lower voltage rated components.

As long as the component value is comparable. With capacitors the normal operating tolerance is +/- 20% so there is a wide latitude in components you can use. With resistors, pay attention to the tolerance. A +/- 10% component may not work as well as a +/- 2% component as the component may be in spec, but way out of tolerance for the circuit.

Going up in voltage by that amount is fine.
Double check the type of that cap, though. Most caps on PC motherboards are low-ESR type. Don't use a cheapie standard cap there.

One thing to note if the cap is close to other components is if it is a 10mm cap or a 12.5mm, a lot of mainboards use 10mm and space can be an issue at times, especially if you get a row of caps.
Also make sure they are rated at 105 degrees.
 
As long as it's a good cap then that's perfectly acceptable!

:D

The biggest problem with motherboard caps is what Ed said - use low ESR when replacing them.

Since you pulled one off another motherboard it should be the low ESR type. If you have to buy them then make sure it specifically is a low ESR type cap.
